CONSTRUCTION MATERIAL WITH VIBRATION-PROOF, SOUND-RPOOF AND HEAT INSULATION FUNCTIONS AND FLOOR STRUCTURAL MEMBER CONTAINING CONSTRUCTION MATERIAL

摘要

PURPOSE: A construction material and a floor structural member containing it are provided to maximize effects of vibration-proof, sound-proof and heat insulation functions as well as simplify a construction work thereof. CONSTITUTION: The construction material comprises a board member(1) for absorbing shock or vibration applied from the outside to remove it; and a synthetic resin sheet(2,3) attached to at least one surfaces of the board member, the sheet having a sound absorbing function and a heat insulation function. The board member includes upper and lower plates(11,12) and partitions(13) spaced apart from each other at regular distances to define an air layer(14) between them. The floor structural member consists of a concrete slab layer, the construction material installed on the concrete slab layer, a lightweight concrete installed on the construction material, and an uppermost finishing device containing a heating piping.
